Lebiasina yepezi, a new lebiasininae (Characiformes: Lebiasinidae) from the Serra Parima-Tapirapecó mountains

Lebiasina yepez a new Lebiasininae with a conspicuous color pattern, is described. The new species is endemic of the headwaters of the rio Negro, rio Branco, and rio Orinoco in the Serra Parima-Tapirapecó Mountains, at the border of Brazil and Venezuela. The new species is readily distinguished from all other Lebiasininae by the presence of four black longitudinal stripes on the trunk, and the triangular shaped dorsal surface of the mesethmoid, lacking lateral projections. The unusual color pattern is contrasted with those of other lebiasinin, as well as members of the pyrrhulinin genus Nannostomus. A close relationship between Lebiasina yepezi and the Gran Sabana (Venezuela) species is suggested based in color pattern features. The present contribution corresponds to a further refutation of the type locality of L. intermedia, as suggested on its description, since Lebiasinins, except L. bimaculata, L. boruca, and L. festae, do not occur in low land waters. © 2011 Sociedade Brasileira de Ictiologia

Checklist dos peixes de \ue1gua doce do Estado de S\ue3o Paulo, Brasil

As espécies de peixes de água doce encontradas no estado de São Paulo distribuem-se entre quatro bacias hidrográficas principais: Alto Paraná, Paraíba do Sul, Ribeira de Iguape e um conjunto de pequenas drenagens costeiras que desembocam diretamente no oceano Atlântico. Como estas bacias drenam áreas com diferentes tipos de vegetação, solos, etc., cada uma tem uma composição de espécies diferente. No Alto Paraná, o grande Rio Paraná e alguns de seus maiores afluentes (Tietê, Paranapanema e Grande) possuem espécies de grande porte que sustentam a pesca comercial e de subsistência, mas 70 a 80% da ictiofauna é composta por espécies de pequeno porte de pequenos riachos, incluindo os de cabeceira, onde muitas são endêmicas. O inventário da ictiofauna foi incrementado através de três projetos de pesquisa apoiados pelo programa BIOTA/FAPESP, mas ainda resta muito trabalho de coleta e descrição de novas espécies de áreas pouco exploradas, como calhas de rios, regiões de cabeceiras, alagadiços em áreas marginais de reservatórios e lagos. A ictiofauna do Estado de São Paulo tem sofrido da ação deletéria de poluição, desmatamento, esgotos urbanos e construção de reservatórios para produção de energia elétrica, etc., de tal forma que atualmente 66 espécies são consideradas ameaçadas em vários níveis, de acordo com os critérios da "International Union for Conservation of Nature and Natural Resources" (IUCN)

Harttia absaberi, a new species of loricariid catfish (Siluriformes: Loricariidae: Loricariinae) from the upper rio Paraná basin, Brazil

A new species of Harttia, tribe Harttiini, is described from tributaries of upper portions of rio Paraná drainage. The new species, the smallest known species of the genus, attaining up to 74.0 mm of standard length, can be distinguished from its congeners by the combination of the following characters: abdomen completely covered by plates, a single preanal plate, plates of the gular area in broad contact with the canal plate. Harttia absaberi is the second species of the genus known from the upper portion of rio Paraná drainage

Uma espécie nova de Harttia, tribo Harttiini, é descrita dos tributários da porção superior da drenagem do rio Paraná. A espécie nova, a menor espécie conhecida do gênero, alcançando até 74,0 mm de comprimento padrão, pode ser diferenciada de suas congêneres pela combinação dos seguintes caracteres: abdômen completamente coberto por placas ósseas, uma única placa preanal, placas da região gular em contato amplo com a placa portadora de canal.

Three new species of Harttia (Loricariidae: Loricariinae) from Serra do Cachimbo, Rio Xingu basin, Pará, Northern Brazil

Three new species of Harttia from the Rio Xingu basin in the region of Serra do Cachimbo, Pará State, Brazil, are described. Harttia rondoni n. sp., H. panara n. sp. and H. villasboas n. sp. were collected in the Rio Curuá, a tributary of Rio Iriri, Rio Xingu drainage. Harttia rondoni was additionally recorded from the Rio Fresco basin, a tributary of the middle Rio Xingu. The three new species represent the first records for the genus in this drainage. Harttia rondoni differs from H. panara and H. villasboas by having the abdomen partially covered by plates. Harttia panara differs from H. rondoni and H. villasboas by having a larger body depth and interorbital distance. Harttia villasboas differs from H. rondoni and H. panara by having the anterior profile of the head elliptical in dorsal view and a more elongated snout. Additionally, the 26 species of Harttia described are organized in three species group based on the pattern of abdominal covering. Copyright © 2018 Magnolia Press
